Palladium bis(2,2,6,6-tetramethyl-3,5-heptanedionate) catalyzed alkoxycarbonylation and aminocarbonylation reactions

Palladium bis(2,2,6,6‐tetramethyl‐3,5‐heptanedionate), a structurally well defined O‐containing transition metal complex, is reported to be an efficient catalyst for alkoxycarbonylation and aminocarbonylation reactions under milder operating conditions. The system tolerated the carbonylative coupling of various aryl halides with phenol/alcohol and amines, providing good to excellent yields of desired products under optimized reaction conditions.

A facile protocol has been developed for the alkoxycarbonylation, and aminocarbonylation reactions using palladium bis(2,2,6,6‐tetramethyl‐3,5‐heptanedionate) complex as an efficient catalyst. The system tolerated the carbonylative coupling of various aryl halides with phenol/alcohol and amines providing good to excellent yields of desired products under optimized reaction conditions.
